4 Claims.

This invention relates to improvements in wicks, and more particularlyto wicks of tubular form adapted to be raised andr lowered bygear-mechanism. 1 f

Heretofore, it has been usual to mount wicks of tubular form inperforated-'metal tubular carrers, the perforations of which carriersintermesh with the usual gear-mechanism employed for raising andlowering the wick for adjusting the same. .This carrier is comparativelyexpensive to make and requires additional expense for the assembly ormounting of-the wick in the carrier for commercial sale or use.

One object of this invention is to provide a tubular wick withlower-cost means in place of the present type of tubular metal carrier,for engagement with the raising-and-lowering gearmechanism.

Another object of this invention is to provide a tubular wick withlow-cost means woven along with the wick when the latter is made, inorder to take the place of the more expensive tubular metal carrier, forlcooperative action with the raising-and-lowering gear-mechanism usuallyemployed with the present type of carrier.

Another object of this invention is to provide an improved wick formedof simple elements readily manufactured and readily assembled to producea durable, efcient construction at minimum cost.

With the above and other objects in view, as will appear to thoseskilled in the art from the present disclosure, this invention includesall features in the said disclosure which are novel over the prior art.

Referring to Figs; l tov 5of`the"drawings, the wick 20? illustrates atubular wick made from a strip ot' wicking shaped into tubular form andhaving the ends or edges 2l abutted and joined together'in any suitableway, as for example, by sewing with stitches 22 of thread or othersuitable material. The wick 2|] has two plys 23 and 24, eachy`ply`having longitudinal textile strands 25 interwoven with transversetextilel strands 26, the two plys being connected by binder-strands 21.Raiser-wires 28 of any suitable'metal, as for example,brass 'of suitablestiffness, such for example', as half-hard brass, extend transverselyaround the wick andare 'interwoven with the longitudinal strands 25,thus providing exposed raiser-wire sections 29 arranged in longitudinalgroups at a suitable acute angle to the vertical to be properly engagedwithfthe teeth of: lgears 3D and 3l, which gears are rigidly secured ytothe shaft 32 rotatably mounted in tube 33, which tube is secured tomembers 34 and 35 respectively secured to the outer tubular wall 36 oithe annular oilchamber 31. A hand-wheel 38 secured to shaft 32 can berotated in one direction or the other, to cause the gear-teeth of gears3|] and 3| engaging the raiser-wire sections 29 to raise or lower thetubular wick, depending on which direction the hand-wheel is rotated.

In the form of the invention illustrated in Figs. 6, 7 and 8, the wick39 includes a lower portion or section 40, and an upper portion orsection 4I. The lower wick-section 49 is formed from a strip of wickingformed'up to tubular form and having its adjacent edge-portions 42suitably joined together as by stitches 43 of thread or the like. Thelower wick-section 4l] is secured to the upper wick-section 4I by havingits top-edge portion 44 joined to the bottom-edge portion 45 of theupper wick-section 4I by suitable means, as by stitches 43 of thread orthe like. The upper wicksection 4l may be of any suitable type, such aswoven or felted construction, either seamless, or seamed ornon-seamless, although the particular form illustrated in the drawingsis seamless.

The particular lower section 40 illustrated in the drawings is a two-plyfabric having plys 41 and 48, each ply having transverse textile strands49 extending transversely around each ply of the wick-section 40 andinterwoven with longitudinally-extending stiifening-wires 50 extendingup and down each ply of the wick-section 4U. The outer or face-ply 41 ofthe wick-section 40 has transverse raiser-wires I extending transverselyaround the wick and interwoven with the longitudinal stiffening-wires50. Binder-strands 52 extend transversely around the Wick-section 4S andserve to connect the two plys together.

In the form of the invention illustrated in Fig. 9, each of theraiser-wires 53 is composed of two wire-strands 54 twisted together.

Referring to Figs. and 11, the tubular wick 55 is made from a strip ofmolded or felted wicking having a strip of screening 55 embedded in theouter surface thereof. The strip of wicking is shaped or formed orrolled up into tubular form and has its adjoining edge-portions 51suitably joined together as by stitches 58 of .thread or the like. Thescreening 56 has raiser-wires 59 extending transversely around the wick,and longitudinal or up-and-down wires 60 are interwoven with the wires59, the wires 60 being arranged at a suitable acute angle to thevertical to bring the raiser-wire` sections 6| in proper position formeshing with the gear-teeth of the raising-and-lowering gears. In makingthe wick 55, the screening 56 is laid on top of the screen of a mold orof the paper machine, and a suitable usual type of suspension of bers ofsulphite pulp and/or cotton and/or asbestos or the like in water ispoured over the screening 56 and over the screen (not shown) of thepaper machine or mold, whereby a strip of wicking similar to thatillustrated in Fig. 11 is produced, with the wire- 40 screen 56 embeddedin one side thereof for a portion of the height' thereof.

Wicks made according to the present invention thus have suitable meanssuch as the raiserwires which cooperate with the raising-and-low- 45ering gears, and, therefore, it is not necessary to employ the usualtype of perforated-metal tubular carriers, which latter are moreexpensive to make and apply to wicks. Applicants wick may, therefore, bereferred to as a carrierless wick.

The invention may be carried out in other specific ways than thoseherein set forth without departing from the spirit and essentialcharacteristics of the invention, and the present embodiments are,therefore, to be considered in all respects as illustrative and notrestrictive, and all changes coming within the meaning and equivalencyrange of the appended claims are intended to be embraced therein.
